This week the can reveal what the outcome of the election could have been under a variety of different voting systems. There are always little charts right after the election showing alternative distributions of seats, but that can only re-arrange votes and seats. It doesn’t show the way people might have voted in a different system, if they knew their vote mattered more. To do that, you have to ask them. This the ERS have done, talking to over 40,000 people about their true party preferences, rather than just the way they cast their vote.
Here’s how the distribution of seats would have been under different systems:
Interesting to see how little things would have improved under an AV system, which suggests the country was right to turn it down – and confirms what a pointless idea it was to put that option to a referendum.
The ERS suggest that this is the “least representative result in UK electoral history”, and that half of all MPs were elected without a majority. A new record was set for an MP elected with the smallest vote share – 24.5%.
